6.1. Enhanced Windows Authentication With Windows Connector

To help secure all data being transferred to and from the Windows server when using the Windows connector, Sun Ray Software also supports the built-in RDP encryption that uses the RC4 cipher, which encrypts data of varying size with a 56-bit or a 128-bit key. Enhanced authentication options are also provided, which include TLS/SSL (with optional server verification) and Network Level Authentication (NLA) using CredSSP. For NLA, Kerberos authentication is used by default, but NT LAN Manager (NTLM) authentication is also provided.

All the available enhanced authentication options protect the Windows session from malicious users and software before a full session connection is established. See Network Security in the Administration Guide for details.
